Application filed December 1, 1915. Serial No. 65,101.

To all whom it may concern:

Be it known that I, WILLIAM J. Bnrsnn, a citizen of the United States, and resident of Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to non-refillable bottles and in the drawing I have shown it applied to the type of bottle covered by my prior Patent No. 1,144,287, dated June 22, 1915, although it will be understood from the following description that it is also applicable to other non-refillable bottles of a different specific construction. The invention involves the use of two separated screens or sieves within the neck of the bottle between the outer guard and the valve. The purpose of the two screens is to prevent the possibility of floating a small particle around the guard through the neck of the bottle and lodging it between the valve and its seat. This would be very difficult to do in any'case but it might be possible by the use of a small piece of cork fastened to the end of a hair. With the two perforated screens having the perforations out of line and the space between the screens being invisible from the outside it would be impossible for anyone to thus float an article into the neck of the bottle and lodge it beneath the valve. Heretofore it has been found practically impossible to make use of a perforated screen beneath the outer guard in a non-refillable bottle for the reason that it has been found that as ordinarily constructed the liquid will not flow through the screen so as to discharge the contents of the bottle when desired. The small perforations seem to prevent the entrance of air to take the place of the discharged liquid and thus the vacuum created by a slight discharge will prevent further flow. After my experiments I have discovered how the screen can be arranged so that it will permit a free flow of the liquid outward and I have further found that by my arrangement I can use two screens without interfering in any way with the free discharge of the liquid. The novel features of the invention will be apparent from the following description taken in connection with the drawing. In the drawing- Figure 1 is a vertical section of a bottle em dying my n en n tanoe so as to allow Specification of Letters Patent. Patented Sept. 10, 1918.

Fig. 2 is a bottom plan view of the guard which is placed at the neck, and

discharge end of the Fig. 3 is a plan view of one of the perforated screens which I use.

As shown in the drawing, lindicates the body of the bottle which is provided with an integral n eek portion 2 The outer section 3 of the neck is made separately and is placed above the portion 2 and secured thereto by the collar l. Between the two sections of the neck there is clamped the valve seat 5 within which fits the tapered valve 6. When the bottle is in upright position the valve is held to its seat by the weight 7 which is flexibly connected to it. Abov e the valve seat 5 and resting on it is the cylindrical spacing mem ber 8 and there is a guard or pro above the cylindrical member 8 tector 9 which is provided across its top with a disk 10 to prevent access to the parts on guard.

My invention the inner side of the relates particularly to the arrangement of the member 8 with reference to the guard 9 and the them of the two perforated separated by the opaque ring interposition between screens 11, 1-2 13 which may be made of cork or other sultable material.

The perforated screen pro ectioai on its under the valve 6 may strike verted so that the valve will the screen.

It will further be observed that the passage through the guard member 9 is enlarged into a practically cylindrical extension immediately thus providing an enlarged screen. Within the g enlarged space I place at intervals, their above the screen 12, space above the uard and within the lugs or projections 16 purpose being to prevent eddying of the liquid in that space and render it more quiescent. and 12 are preferably The two screens 11 separated some discon'siderable space between them. In practice it will be found that a distance of abou will be satisfactory t a quarter of an inch The ring 13 being of opaque material it is impossible for anyone to see between the two screens.
